UNITED STATES PATENT OFFICE.

BLUE-FLAME GAS-SAVER.

Application filed July 24, 1918.

To all whom it may concern:

Be it known that I, JAMEs E. RYAN, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented new and useful Improvements in Blue-Flame Gas-Savers, of which the following is a specification.

This invention coniprehends generally improvements in gas-stove burners, and more particularly has reference to a blue flame gas saver.

It is the primary aim and object of this invention to provide a device of the above mentioned character designed to be seated on and positioned in close spaced relation to the top of a gas burner for assuring of a proper mixture of air with the gas issuing from the burner for the proper deoarbonizing of the gas thereby producing a rather intense heat with a relatively small amount of gas.

As an equally important object the present invention contemplates the provision of a device of the above mentioned character designed to act as a gas flame evener so as to obviate the escape of gas around the sides thereof and in addition is capable of equally distributing the flame on the bottom of a receptacle positioned on the gas-stove above the burner, thereby avoiding the burning of the receptacle. I

More particularly the present invention embraces the provision of a device of the character mentioned designed to be readily and removably seated on the majority of gas burners now in use, and is of such construction as to provide for the expansion and contraction of the body of the device when the latter is in use.

Among the other aims and objects of this invention may be recited the provision of a device of the character described with a view to compactness, and in which the number of parts are few, the construction simple, and the post of production low and the efiiciency hi ther improvements and novel details in the construction and arrangement of the various parts of the apparatus will be brought out more in detail in the description to follow, which for a clear understanding of the invention should be considered in conneotion with the accompanying drawings formin a part hereof, and wherein is disclosed for the purpose of illustration 2. convenient and satisfactory embodiment of the Specification of Letters Patent.

Serial No. 246,529.

invention. It is to be noted in this connection that minor changes in the construction and arrangement of parts may be made without departing from the principle of operation of the various parts.

The invention is clearly illustrated in the accompanying drawings, in which 2 Figure l is a side elevation of the invention in position on a round gas burner, in section.

Fig. 2 is a top plan view of the invention.

Fig. 3 is a perspective detail showing a modified form of the device applied on a portion of a star-shaped burner.

Similar characters of reference are employed in all of the above described views, to indicate corresponding parts.

Referring now, more particularly, to the accompanying drawings there is illustrated a burner 1 which may be of the round or annular shaped top, while seated on the burner and positioned above the same is the improved blue flame gas saver, indicated in its entirety by the numeral 2. In the present instance this improved gas saver consists of a disk-like body 3 formed with a central raised portion or hood 4 which in turn is provided with a gas outlet opening 5 centrally thereof. The hood is also formed with a plurality of radially arranged slots 6, the sides of which taper toward the center while also formed between every other slot in the hood is a pair of openings 7 which are arranged radially relative to each other and to the slots 6. Still further the body is provided with a circle of open ings 8 positioned near the outer edge thereof and all these openings and slots serve as gas outlets and assure of an even flame striking the bottom of the receptacle which is adapted to be disposed above the same, as is, apparent.

In order to assure of the proper seating of the device on the burner a plurality of radially arranged lugs 9 depend from the body and have their lower curved edges formed with a series of notches 10 for sitting on the upper edge of the burner 1.

In Fig. 3 there is shown a slightly moditied form of the invention. In this instance instead of being designed for engagement with a round burner the device 11 is designed to be seated on a burner of the star type, as indicated by the numeral 12 and in accomplishing this purpose instead of providing lugs radially of the disleshaped body, a plurality of lugs 13 preferably oppositely disposed to each other depend from the under surface of the body and are formed with notches 14 for the straddling of the lugs about the radial branches of the burner.

In use, assuming that the parts have been designed as described, and as illustrated in the drawings, the flame from the gas burner is covered by the disk-shaped body 3 and is deflected to the center beneath the hood 4. Of course, some of the gas passes through the circle of openings 8 disposed directly above the burner while the flame which is concentrated beneath the hood is equally distributed on the bottom of a receptacle adapted to be disposed above the device by the provision of the radial slots and series of openings and by the central opening 5. These openings and slots in the hood of course, cooperate with the openings 8 and assure of the proper equalization of the flame. In addition, by reason of the fact that the disk-like body is slightly spaced above the burner, the in-draft which passes between the burner and the disk-like body mixes with the gas for the decarbonizing thereof. When the device has been in use for a time the gas may be turned out and it will retain some of the heat for ten or fifteen rninutes, not enough heat however, to boil or broil, but sufiicient to keep warm the contents of the receptacle, not shown.

WVhat is claimed is A device of the character set forth consisting of a disk-like body formed with a central hood, the body being provided with a plurality of openings and slots and carrying on its under face a plurality of radially arranged lugs, the lower edges of which are arched inwardly and formed with series of notches to engage the upper face of a gas burner as herein shown and specified.

In testimony whereof I aflix my signature.

JAMES E. RYAN.
